Report

The Bubble Nebula, ngc7635, formed by the hot stellar wind of a massive young star blowing against the surrounding giant molecular cloud creating a glowing 7 light year wide bubble.

There was a lot of dew during capture as you can see from the blue halo around the star. When I saw that in the subs I was worried that there wouldn't be any good data in there, but the data emerged and I liked the way the blue halo contrasted with the red of the hydrogen alpha so I left it in.
